Benefits of technology

[0023] An object of the present invention is to eliminate or significantly reduce one or more of the problems occurring in connection with manufacture and use of floorboards with decorative embedded joint portions. A further object of the invention is to provide a rational and cost-efficient manufacturing method for manufacturing floor elements, floor panels and floor boards.
[0027] The invention is also particularly suited for use with floorboards having mechanical joint systems which allow exact positioning of the floorboards relative to each other without visible joint gaps in the decorative joint portion. Such locking systems give the decorative joint portion a natural appearance.
[0032] According to a second aspect of the invention, the core can be used to create the decorative embedded joint edge portion, either by the core having suitable properties, or by part of or the entire core before laminating, or after machining, being machined in a convenient manner so as to provide a decorative appearance or better properties in order to counteract moisture or wear.

Problems solved by technology

Such high quality core materials, however, are not used for decoration purposes since they are concealed by the surface layer.

Embodiment Construction

[0045] FIGS. 1a-d show in four steps manufacture of a floorboard. FIG. 1a shows the three basic components surface layer 31, core 30 and balancing layer 32. FIG. 1b shows a floor element 3, where surface layer and balancing layer have been applied to the core. FIG. 1c shows how floor panels 2 are made by dividing the floor element. FIG. 1d shows how the floor panel 2 after machining of its edges obtains its final shape and becomes a completed floorboard 1 with a joint system 7, 7', which in this case is mechanical, on the long sides 4a, 4b.

[0046] FIG. 2a shows manufacture of high pressure laminate. A wear layer 34 of a transparent material with great wearing strength is impregnated with melamine with aluminum oxide added. A decorative layer 35 of paper impregnated with melamine is placed under this layer 34. One or more reinforcing layers 36a, 36b of core paper impregnated with phenol are placed under the decorative layer 35 and the entire packet is placed in a press where it cures ...

Abstract

Floorboards consisting of a core and a surface layer with decorative joint edge portions which are formed by removing the surface layer.

Description

[0001] The invention generally relates to the field of decorative grooves for floorboards. The invention relates to floorboards provided with such decorative grooves and methods for making such floorboards. The invention is particularly suited for use in mechanical locking systems integrated with the floorboard of the type described and shown, for example, in WO9426999, WO9966151, WO9966152, SE 0100100-7 and SE0100101-5 (owned by Vlinge Aluminium AB) but is also usable in optional joint systems which can be used to join floors.[0002] More specifically, the invention relates above all to floors of the type having a core and a decorative surface layer on the upper side of the core.FIELD OF APPLICATION OF THE INVENTION[0003] The present invention is particularly suitable for use in floating floors, which are formed of floorboards which are joined mechanically with a joint system integrated with the floorboard, i.e. mounted at the factory, and are made up of one or more preferably moist...
